Copy Files Step Issues

[Buildboy]

Hello :-)
I was just wondering if I can copy multiple folders and files at the smae time using this action, if I try to copy 2 specific folder located on root of drive C: and a file which is located in the root of C: as well, it doesn't work, this is what I have:

\Test1
\Test2
test.bld
(Zero file copied)

but if I have

\Test1
\Test2

or
test.bld
test1.bld

they get copied, is this a limitation of the copy step ( meaning only file or only folders in each step) or I am missing something?

Thank you all in advance :-)
